Answer:

The answer is 9/16.

Step-by-step explanation:

Using Indices Law,

${( \frac{a}{b}) }^{n} ⇒ \frac{ {a}^{n} }{ {b}^{n} }$

So for this question :

${ (\frac{3}{4}) }^{2}$

$= \frac{ {3}^{2} }{ {4}^{2} }$

$= \frac{3 \times 3}{4 \times 4}$

$= \frac{9}{16}$

A car rental company charges a one-time application fee of 40 dollars, 55 dollars per day, and 13 cents per mile for its cars. A

liberstina [14]

Answer:

A) C(d,m) = 40 + 55d + 0.13m

B) $448

Step-by-step explanation:

Let 'd' be the number of days and 'm' the number of miles driven.

A) The cost function that describes a fixed amount of $40, added to a variable amount of $55 per day (55d) and a variable amount of 13 cents per mile (0.13m) is:

$C(d,m) = 40 +55d +0.13m$

B) If d = 5 and m =600, the total cost is:

$C(5,600) = 40 +55*6 +0.13*600\\C(5,600)=\$448$

The cost is $448.
